A satellite orbits the Earth once every 120 minutes.
The satellite is in a state of free fall. What is meant by the term free fall? How can the height of the satellite stay constant if the satellite is in free fall? [3 marks]

So is this correct:

Free-fall: when the only force acting on an object is the gravitational force
- as the force is acting ppd to direction of motion, no work is done on the satellite
- the satellite moves in a circle at a constant speed
